摘要：
Time varying channels will degrade the performance of orthogonal frequency division multiplexing (OFDM) due to the interchannel interference (ICI). In this paper, we propose the channel estimation for multiple input multiple output (MIMO)-OFDM with time varying channels based on the grouped and equi-spaced pilot tones. Specifically, we approximate the time varying channels to the polynomials. Additionally, we propose the detection method for the OFDM with ICI. © 2006 IEEE.
